Furthermore, in the specification, "on..." means located above or below the target component, and does not mean that it must be located on the top above based on gravity.
[0024] The following will describe in detail some implementation manners of the present utility model in conjunction with the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.
[0025] Such as Figure 1As shown, an embodiment of the present utility model provides a magnetic control charging device 10. The magnetic control charging device 10 includes, for example, a cover body 110 and a housing 100. The housing 100 is connected to the cover body 110, and a magnetic attracting member 111 is provided on the cover body 110. The magnetic control charging device 10 is, for example, a charging socket on a charging pile capable of charging an electric vehicle, an electric bicycle, etc. When an external device such as an electric vehicle or an electric bicycle needs to be charged, for example, the cover body 110 needs to be opened to connect the charging plug to the magnetic control charging device 10. At this time, the magnetic control charging device 10 outputs voltage to the external charging plug.
[0026] Referring to Figure 2 , the magnetic control charging device 10 includes, for example, a main control circuit 200, a status monitoring circuit 300, and a voltage output circuit 400. The main control circuit 200, the status monitoring circuit 300, and the voltage output circuit 400 are, for example, all provided inside the housing 100, and the status monitoring circuit 300 and the voltage output circuit 400 are electrically connected to the main control circuit 200. For example, the status monitoring circuit 300 and the voltage output circuit 400 are electrically connected to the main control circuit 200 through connection lines.
[0027] Specifically, the status monitoring circuit 300 is used to sense the position of the magnetic attracting member 111 and send a first position signal to the main control circuit 200 when the magnetic attracting member 111 is relatively far away from the status monitoring circuit 300. The status monitoring circuit 300 is also used to send a second position signal to the main control circuit 200 when the magnetic attracting member 111 is relatively close to the status monitoring circuit 300. For example, the status monitoring circuit 300 is an inductor such as a magnetic sensor that can sense the magnetic attracting member 111. Referring to Figure 1 , the status monitoring circuit 300 is, for example, disposed opposite to the magnetic attracting member 111. Thus, when the position of the magnetic attracting member 111 provided on the cover body 110 changes, it can be understood that the cover body 110 is opened or closed at this time. That is, when the cover body 110 is closed, the magnetic attracting member 111 on the cover body 110 is, for example, relatively close to the status monitoring circuit 300. At this time, the magnetic control charging device 10 is necessarily separated from the external charging plug, that is, the magnetic control charging device 10 stops outputting voltage. When the cover body 110 is opened, the magnetic attracting member 111 on the cover body 110 is, for example, relatively separated from the status monitoring circuit 300. At this time, the magnetic control charging device 10 outputs voltage.
[0028] The main control circuit 200 is configured to generate a first voltage signal according to the first position signal and send it to the voltage output circuit 400. The main control circuit 200 is also configured to generate a second voltage signal according to the second position signal and send it to the voltage output circuit 400. The main control circuit 200 may include, for example, a microcontroller, and the microcontroller may specifically be, for example, a Central Processing Unit (CPU) or a Microcontroller Unit (MCU). In addition, the main control circuit 200 also includes, for example, a storage unit connected to the microcontroller. The storage unit may be a high-speed Random Access Memory (RAM) or a non-volatile memory (NVM), such as a disk memory. Optionally, the storage unit may also be a storage device independent of the foregoing main control circuit 200, and the present application does not limit this.
[0029] Continuing from the above, the voltage output circuit 400 is configured to output a voltage according to the first voltage signal, and the voltage output circuit 400 is also configured to stop outputting the voltage according to the second voltage signal. For example, the voltage output circuit 400 includes a relay. When the cover 110 is opened, that is, when the magnetic attracting member 111 on the cover 110 is relatively separated from the state monitoring circuit 300, for example, the main control circuit 200 controls the relay to output a voltage.
[0030] In a specific embodiment, refer to Figure 2, the magnetically controlled charging device 10 further includes an identification circuit 500, which is disposed inside the housing 100 and electrically connected to the main control circuit 200, for example. Specifically, the identification circuit 500 is configured to identify user identity information when the magnetic member 111 is relatively far away from the status monitoring circuit 300, and send charging information to the main control circuit 200 when the user information is consistent with the preset information. The main control circuit 200 is configured to start charging after receiving the charging information, generate a first voltage signal according to the first position signal, and send it to the voltage output circuit 400. For example, the identification circuit 500 is an NFC (Near Field Communication) identification circuit. The NFC identification circuit includes an NFC chip, etc. The NFC chip is an NFC chip in the prior art. The NFC identification circuit can identify the user's membership card, etc., and send charging information to the main control circuit 200 when the identification is consistent, that is, when it is determined that the membership card can be used. The main control circuit 200 starts charging after receiving the charging information and controls the voltage output circuit 400 to output voltage. For example, the above-mentioned user's membership card is a chip card that can be identified by the NFC chip. Specifically, after the user opens the cover 100, the user contacts the membership card with the identification circuit 500 for the identification circuit 500 to identify. When the identification circuit 500 successfully identifies, the main control circuit 200 starts charging, and the magnetically controlled charging device 10 can charge the user's charging plug.
[0031] For example, when the user needs to charge their electric vehicle or electric bike, they need to first open the cover 110 of the magnetically controlled charging device 10 so that the charging plug can be connected to the magnetically controlled charging device 10. The user also needs to contact their membership card with the identification circuit 500 for the identification circuit 500 to identify. At this time, the status monitoring circuit 300 senses that the magnetic member 111 on the cover 110 is relatively far away from the status monitoring circuit 300, so the status monitoring circuit 300 sends a first position signal to the main control circuit 200. If the identification circuit 500 successfully identifies, the main control circuit 200 starts charging and controls the voltage output circuit 400 to output voltage, so as to charge the user's electric vehicle or electric bike. When the user needs to stop charging, the charging plug is relatively separated from the magnetically controlled charging device 10 and the cover 110 is closed. At this time, the status monitoring circuit 300 senses that the magnetic member 111 on the cover 110 is relatively close to the status monitoring circuit 300, so the status monitoring circuit 300 sends a second position signal to the main control circuit 200. The main control circuit 200 stops charging and controls the voltage output circuit 400 to stop outputting voltage.
[0032] Further, refer to Figure 2, the magnetic control charging device 10 further includes a wireless transmission circuit 800, and the wireless transmission circuit 800 is electrically connected to the main control circuit 200. The main control circuit 200 is configured to generate first usage status information according to the first position signal and output the first usage status information through the wireless transmission circuit 800; the main control circuit 200 is further configured to generate second usage status information according to the second position signal and output the second usage status information through the wireless transmission circuit 800. For example, the wireless transmission circuit 800 can be, for example, a WIFI network transmission unit, a 5G mobile communication unit, or a Bluetooth communication unit, and is used to transmit the first usage status information and / or the second usage status information to a smart terminal such as a smart phone, so as to facilitate the user to understand the current usage status of the magnetic control charging device 10, that is, whether the current magnetic control charging device 10 is still charging.
[0033] See Figure 3 , the magnetic control charging device 10 further includes a timing circuit 600. The timing circuit 600 is disposed inside the housing 100 and is electrically connected to the main control circuit 200. The timing circuit 600 includes, for example, a timing unit 610 and a first reminder unit 620, and the timing unit 610 and the first reminder unit 620 are respectively electrically connected to the main control circuit 200. The timing unit 610 is configured to time the voltage output by the voltage output circuit 400 to obtain a timing time. The main control circuit 200 is configured to send a first reminder control signal to the first reminder unit 620 when the timing time is equal to a preset charging time, and the first reminder unit 620 is configured to issue a reminder according to the first reminder control signal. For example, the main control circuit 200 can obtain the preset charging time through the wireless transmission circuit 800. That is, the user can set the preset charging time to 1 hour, for example, or the developer can build in the preset charging time to 1 hour, 2 hours, etc. For example, when the preset charging time is set to 1 hour, the reminder unit 620 issues a reminder every 1 hour. The timing unit 610 can be, for example, a timer or a timing chip. It should be noted that in a specific implementation manner of this embodiment, the timing unit 610 can be integrated on the main control circuit 200 without separately setting the timing unit 610, and the present application does not specifically limit this. The reminder unit 620 can be, for example, a buzzer, and the reminder unit 620 can also be, for example, other devices that can remind the user, and the present application does not limit this.
[0034] See again Figure 3, in a specific implementation manner of the embodiment of the present utility model, the magneto-controlled charging device 10 further includes, for example, a timing circuit 700. The timing circuit 700 is disposed inside the housing 100 and electrically connected to the main control circuit 200. The timing circuit 700 includes a timing unit 710 and a second reminder unit 720. The timing unit 710 and the second reminder unit 720 are respectively electrically connected to the main control circuit 200. The timing unit 710 is used to obtain the current time. The main control circuit 200 is used to determine whether the current time is the same as the predetermined time, and when the current time is the same as the predetermined time, send a second reminder control signal to the second reminder unit 720. The second reminder unit 720 is used to issue a reminder according to the second reminder control signal. Specifically, the timing unit 710 may be, for example, a clock chip. It should be noted that, in a specific implementation manner of this embodiment, the timing unit 710 may be integrated on the main control circuit 200 without separately setting the timing unit 710, and the present application does not specifically limit this. For example, the main control circuit 200 may obtain the predetermined time through a wireless transmission circuit 800, that is, the user can set the predetermined time by himself. For example, if the user sets 15:00, the second reminder unit 720 will issue a reminder at 15:00. The reminder unit 720 may be, for example, a buzzer, and the reminder unit 720 may also be other devices that can remind the user. The present application does not limit this.
[0035] Further, referring again to Figure 2, the magnetic control charging device 10 further includes a voice interaction circuit 900, which is disposed inside the housing 100 and electrically connected to the main control circuit 200. The main control circuit 200 is further configured to generate a first voice control instruction according to the first position signal and send the first voice control instruction to the voice interaction circuit 900; the voice interaction circuit 900 is configured to generate a first voice signal according to the first voice control instruction and play the first voice signal. The main control circuit 200 is further configured to generate a second voice control instruction according to the second position signal and send the second voice control instruction to the voice interaction circuit 900; the voice interaction circuit 900 is configured to generate a second voice signal according to the second voice control instruction and play the second voice signal. Specifically, the voice interaction circuit 900 includes a voice output unit and a speaker. The voice output unit is electrically connected to the main control circuit and the speaker. The housing 100 is provided with a voice output hole, and the speaker is disposed at the voice output hole. For example, the voice output unit may be a voice encoding chip. Of course, the voice interaction circuit 900 further includes a power amplifier circuit, which is disposed between the voice output unit and the speaker and electrically connected to the voice output unit and the speaker. The present application does not limit this.
[0036] In summary, the magnetic control charging device provided by the embodiment of the present invention is provided with a state monitoring circuit, avoiding the use of a mechanical switch in the charging socket. Through the position sensing of the magnetic attracting member by the state monitoring circuit, it can be known in time whether the charging plug is charging through the closing condition of the cover body, so as to control the voltage output circuit to output voltage in time, solving the problems of low safety factor and low service life of the existing charging socket caused by the use of a mechanical switch.
